Lesley Chow: A better way to rebuild cartilage

If you’re able to walk without pain, give a silent shout-out to your cartilage. 

Every time you take a step, this flexible tissue absorbs the load and transfers it to the bone, allowing you to move freely. But unlike bone, if cartilage gets damaged—by injury, wear and tear, or inflammation—it can’t regenerate. Over time, the damaged tissue degrades, and walking becomes progressively more painful as the bones come in contact with each other.

A novel way to watch paint dry

It’s often the first thing we notice about a vehicle, and it reveals a lot: how new (or not) the vehicle is, how it’s been cared for, where it’s been driven. 

“Consumers are extremely picky regarding the quality of the paint job on any car they purchase, new or old, and the 10- to 20-year appearance of a car depends on 10 to 20 critical minutes of application and drying,” says James Gilchrist, a professor of chemical and biomolecular engineering at Lehigh University’s P.C. Rossin College of Engineering and Applied Science.
